Cooling (Figure 1)Low pressure liquid refrigerant from the expansion valve (TEV) enters the counter-flow cooler tubes and is evaporated by the heatenergy absorbed from the chilled water passing through the shell. The refrigerant leaves the cooler in a saturated vapour state.

High pressure liquid refrigerant, from the condenser, enters the suction line heat exchanger shell and superheats the refrigerantvapour entering the tubes from the cooler. The low temperature liquid refrigerant, leaving the exchanger to the cooler, has beensub-cooled by the refrigerant vapour in the exchanger tubes.

Low-pressure superheated vapour enters the compressor where pressure and superheat are increased. High pressure vapour ispassed through the oil separator where compressor oil is removed and recirculated to the compressor via the oil cooler. The highpressure oil-free vapour is fed to the air cooled condenser coil and fans where the heat is removed. The high pressure liquidrefrigerant returns to the expansion valve via the suction line heat exchanger.

Optional Heat Recovery (Figure 1a)If the warm water flow switch detects water flow the heat recovery pressure regulating valves are energised. The valves allowhigh-pressure superheated refrigerant, from the oil separators, to enter the twin circuit heat recovery plate heat exchanger. Therefrigerant is partially condensed as the warm water absorbs heat energy.

The valves are de-energised when the leaving warm water temperature sensor registers the high point of the set point dead band. Ifwater flow is maintained the valves are re-energised if the temperature sensor registers the low point of the set point dead band.

SELECTION GUIDEDATA REQUIREDTo select a YORK YCAS chiller the following information isrequired:

1. Required cooling capacity.

2. Design chilled water entering and leaving temperatures.

3. Design water flow rate if one of the temperatures in item 3are unknown.

4. Design condenser entering air temperature. This willnormally be the design summer ambient air temperatureunless location or other factors have an influence.

5. Altitude above sea level.

6. Design cooler fouling factor.

7. Static pressure resistance against condenser entering andleaving air flow (where ducts, louvres, attenuators, etc., areused) at full unit air volume.

Note: Items 1, 2 and 3 must be linked by the following formulae:

Cooling Capacity (kW) = Range (°C) x Flow (litres/sec) x 4.18

Where:Range = Entering liquid temperature - Leaving liquidtemperature.

CHILLER SELECTION METHOD1. Determine the correct size of chiller by selecting the model

which most closely matches the required capacity at thedesign conditions of leaving water temperature andentering air temperature (Table 7).

2. Apply correction factors for fouling factor (Table 3) andaltitude & fan application (Tables 4 & 5) to the capacity andpower values from the capacity tables (Table 7). Ensure thecorrected capacity is still sufficient for requirements.

3. Using the corrected capacity of the selected chiller adjustthe design temperature range, or flow rate, to balance theformulae shown in “Data Required”.

4. Physical and electrical data can now be determined fromTables 9 and 10.

5. Always re-check that selections fall within the designlimitations specified in Table 2.

COOLING ONLY CHILLER SAMPLE SELECTIONA chiller is required to cool water from 12°C to 7°C having acooling capacity of 575 kW at a design flow rate of 28 l/s. Otherdesign conditions applying are:

Ambient air entering condenser: 35°CFouling factor: 0.044 m² °C./kWAltitude: Sea levelCondenser air restriction: None

From a cursory examination of Capacity Table 7, a model0605EB gives approximately the required capacity:

Capacity = 584 kWCompressor power = 179.7 kW

No correction factors apply therefore, after calculating the flowrate, the conditions will be as follows:

Cooling capacity: 584 kWWater temperature: 12°C to 7°C (Range = 5°C)Water flow rate: 27.95 I/sCompressor power: 179.7 kW

All values are within the operating limits in Table 2. FromPressure Drop Graph (Figure 2), YCAS0605EB cooler waterpressure drop = 36.7 kPa at the calculated flow of 27.95 l/s.

OPTIONAL HEAT RECOVERY SAMPLE SELECTIONA chiller is required to cool water from 12°C to 7°C having acooling capacity of approximately 575 kW at a design flow rateof 28 l/s. Other design conditions applying are:

Ambient air entering condenser: 35°CFouling factor: 0.044 m² °C./kWAltitude: Sea levelCondenser air restriction: NoneRequired leaving Temperature 50°CHot water temperature range 12°C

A model 0605EB meets the cooling requirements, see sampleselection opposite.

From Table 8 a model 0605EB gives the following data whenproviding hot water at 50°C.

LWT Cool (kW) Power (kW) Heat (kW)

7°C 510 226 393

The heating capacity should be corrected for the hot watertemperature range Table 6: 393 kW x 1.02 = 400.8

Heat recovery water flow: 400.8 = 7.99 l/s12°C x 4.18

Heat recovery pressure drop from graph (Figure 3) is 46 kPa atthe calculated flow of 7.99 l/s.

The water pressure drop values shown in figures 3 and 4 are fortwo refrigerant circuit models with flow rates based on 10°C hotwater temperature range.

On four refrigerant circuit models two heat recovery condensersor two pairs of desuperheaters are fitted. Both options are tohave their heat exchanger water circuits connected in parallel.

When connected in this configuration the water flow will beequally divided through the heat exchangers, therefore the totalflow should be divided by 2 when calculating the pressure drop.
